SlickNSF is an older NSF player I made by request. Instead of being a Winamp plugin like NotSo
Fatso, it's a standalone app. The main focus of SlickNSF is to be as light-weight as possible, and to provide a trace logger for debugging
NSFs (unlike NotSo, which has no tracelogger and is a bit more demanding). However, the sound quality doesn't match NotSo's, it lacks several of
the features NotSo offers, and doesn't emulate all the expansion chips like NotSo does.

If you're an NSF ripper, SlickNSF can be a good tool for helping to debug/clean up your rips. But if you're just looking
for casual NSF playback, I'd recommend going with NotSo Fatso instead.
